Caesarean section is associated with moderate-to-severe postoperative pain, which can influence postoperative recovery and patient satisfaction as well as breastfeeding success and mother-child bonding. The aim of this systematic review was to update the available literature and develop recommendations for optimal pain management after elective caesarean section under neuraxial anaesthesia. A systematic review utilising procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. Randomised controlled trials published in the English language between 1 May 2014 and 22 October 2020 evaluating the effects of analgesic, anaesthetic and surgical interventions were retrieved from MEDLINE, Embase and Cochrane databases. Studies evaluating pain management for emergency or unplanned operative deliveries or caesarean section performed under general anaesthesia were excluded. A total of 145 studies met the inclusion criteria. For patients undergoing elective caesarean section performed under neuraxial anaesthesia, recommendations include intrathecal morphine 50-100 µg or diamorphine 300 µg administered pre-operatively; paracetamol; non-steroidal anti-inflammatory drugs; and intravenous dexamethasone administered after delivery. If intrathecal opioid was not administered, single-injection local anaesthetic wound infiltration; continuous wound local anaesthetic infusion; and/or fascial plane blocks such as transversus abdominis plane or quadratus lumborum blocks are recommended. The postoperative regimen should include regular paracetamol and non-steroidal anti-inflammatory drugs with opioids used for rescue. The surgical technique should include a Joel-Cohen incision; non-closure of the peritoneum; and abdominal binders. Transcutaneous electrical nerve stimulation could be used as analgesic adjunct. Some of the interventions, although effective, carry risks, and consequentially were omitted from the recommendations. Some interventions were not recommended due to insufficient, inconsistent or lack of evidence. Of note, these recommendations may not be applicable to unplanned deliveries or caesarean section performed under general anaesthesia.

Review
BACKGROUND
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel intraperitoneal drug delivery method of low-dose chemotherapy as a pressurized aerosol in patients affected by peritoneal cancer of primary or secondary origin. We performed a systematic review and meta-analysis with the aim of assessing the feasibility, safety, and efficacy of PIPAC.
METHODS
A systematic literature search was performed using Medline and Web of Science databases from 1 January 2011, to inception, to 31 December 2021. Data were independently extracted by two authors. The Newcastle-Ottawa Scale was used to assess the quality and risk of bias of studies. Meta-analysis was performed for pathological response, radiological response, PCI variation along treatment, and for patients undergoing three or more PIPAC. Pooled analyses were performed using the Freeman-Tukey double arcsine transformation, and 95% CIs were calculated using Clopper-Pearson exact CIs in all instances.
RESULTS
A total of 414 papers on PIPAC were identified, and 53 studies considering 4719 PIPAC procedure in 1990 patients were included for analysis. The non-access rate or inability to perform PIPAC pooled rate was 4% of the procedures performed. The overall proportion of patients who completed 3 or more cycles of PIPAC was 39%. Severe toxicities considering CTCAE 3-4 were 4% (0% to 38.5%). In total, 50 studies evaluated deaths within the first 30 postoperative days. In the included 1936 patients were registered 26 deaths (1.3%). The pooled analysis of all the studies reporting a pathological response was 68% (95% CI 0.61-0.73), with an acceptable heterogeneity (I 28.41%, = 0.09). In total, 10 papers reported data regarding the radiological response, with high heterogeneity and a weighted means of 15% (0% to 77.8%). PCI variation along PIPAC cycles were reported in 14 studies. PCI diminished, increased, or remained stable in eight, one and five studies, respectively, with high heterogeneity at pooled analysis. Regarding survival, there was high heterogeneity. The 12-month estimated survival from first PIPAC for colorectal cancer, gastric cancer, gynecological cancer and hepatobiliary/pancreatic cancer were, respectively, 53%, 25%, 59% and 37%.
CONCLUSIONS
PIPAC may be a useful treatment option for selected patients with PM, with acceptable grade 3 and 4 toxicity and promising survival benefit. Meta-analysis showed high heterogeneity of data among up-to-date available studies. In a subset analysis per primary tumor origin, pathological tumor regression was documented in 68% of the studies with acceptable heterogeneity. Pathological regression seems, therefore, a reliable outcome for PIPAC activity and a potential surrogate endpoint of treatment response. We recommend uniform selection criteria for patients entering a PIPAC program and highlight the urgent need to standardize items for PIPAC reports and datasets.

Review
AIM
Recurrence after surgery for Crohn's disease is common. Anastomotic configuration may influence recurrence and the mesentery may be key. Recently the Kono-S anastomosis and radical mesenteric excision have been proposed as methods of reducing recurrence. We analysed the literature pertaining to these novel techniques.
METHOD
We searched MEDLINE, Embase and the Cochrane Library for, and selected, studies evaluating Kono-S anastomosis and/or radical mesenteric excision in Crohn's disease. We assessed methodological quality and risk of bias using the Cochrane risk of bias tool for randomized controlled trials and the Joanna Briggs Institute tool for nonrandomized trials. A narrative synthesis was used to summarize the findings.
RESULTS
Nine studies (896 patients) were identified. Apart from one randomized controlled trial with a low risk of bias the overall level of evidence was poor (Grade IV). The Kono-S anastomosis was associated with a lower incidence of endoscopic and surgical recurrence (0%-3.4% vs 15%-24.4% respectively). Complications, particularly anastomotic leak rate, were also lower (1.8% vs 9.3% respectively). Evidence from a single poor quality study suggested that mesenteric excision may reduce surgical recurrence rates compared with mesentery preservation.
CONCLUSION
The existing literature suggests that the Kono-S anastomosis is safe and may reduce endoscopic and surgical recurrence, but level of evidence is mainly poor. One element of the Kono-S technique, preservation of the mesentery, may be detrimental to recurrence. Further, higher quality, studies are required to investigate these techniques. Such studies should consider the impact of the degree of mesenteric resection in addition to the anastomosis on disease recurrence.

Review
We reviewed neovaginal colonization and inflammatory patterns, and factors that may impact this. A systematic review of the neovaginal microbiome was conducted in concordance with PRISMA guidelines through October 2021. Thirteen articles were included, totaling 458 patients. Neovaginal constructions were most commonly performed with penile and scrotal skin grafts, sigmoid segments, and peritoneal grafts. The neovaginal microflora identified were generally polymicrobial and shared similarities with the native tissue. Nine studies identified Lactobacillus: 5 of 6 for penile skin, 1 of 3 for sigmoid, 1 of 1 for peritoneum, and 2 of 3 for other graft types, suggesting that the neovagina may support Lactobacillus either innately, via rectal migration or oral probiotic supplementation. A polymicrobial, bacterial vaginosis-like environment was found in 9 studies. Inflammatory markers were also described: 2 of 6 for penile skin, 2 of 3 for sigmoid, 0 of 1 for peritoneum, and 1 of 3 for other graft types. Scant data were available on the impact of postsurgical duration, oral hormones, dilating, sexual practices, or douching on the neovaginal microbiome. Understanding and optimizing the polymicrobial neovaginal microenvironment may improve surgical outcomes, specifically inflammatory, pain, and infectious. Future research should focus on standardizing testing, classification systems, and treating neovaginal dysbiosis.

Review
BACKGROUND
Minimally invasive surgery has been used for both de novo insertion and salvage of peritoneal dialysis (PD) catheters. Advanced laparoscopic, basic laparoscopic, open, and image-guided techniques have evolved as the most popular techniques. The aim of this guideline was to develop evidence-based guidelines that support surgeons, patients, and other physicians in decisions on minimally invasive peritoneal dialysis access and the salvage of malfunctioning catheters in both adults and children.
METHODS
A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons reviewed the literature since the prior guideline was published in 2014 and developed seven key questions in adults and four in children. After a systematic review of the literature, by the panel, evidence-based recommendations were formulated using the Grading of Recommendations Assessment, Development and Evaluation approach. Recommendations for future research were also proposed.
RESULTS
After systematic review, data extraction, and evidence to decision meetings, the panel agreed on twelve recommendations for the peri-operative performance of laparoscopic peritoneal dialysis access surgery and management of catheter dysfunction.
CONCLUSIONS
In the adult population, conditional recommendations were made in favor of: staged hernia repair followed by PD catheter insertion over simultaneous and traditional start over urgent start of PD when medically possible. Furthermore, the panel suggested advanced laparoscopic insertion techniques rather than basic laparoscopic techniques or open insertion. Conditional recommendations were made for either advanced laparoscopic or image-guided percutaneous insertion and for either nonoperative or operative salvage. A recommendation could not be made regarding concomitant clean-contaminated surgery in adults. In the pediatric population, conditional recommendations were made for either traditional or urgent start of PD, concomitant clean or clean-contaminated surgery and PD catheter placement rather than staged, and advanced laparoscopic placement rather than basic or open insertion.

Review
Autoimmune diseases manifest in genetically predisposed individuals exposed to certain triggers that aggravate immune dysfunction and result in an exacerbated immune response in the form of hyperactivity to both the humoral and cell-mediated response. The devastating reality apart from the severity of the disease is that multiple immune diseases could co-occur, increasing the patient's physical, psychological, and financial burden. Autoimmune diseases are utterly deranging. One of the dreadful autoimmune diseases is systemic lupus erythematosus (SLE). SLE is a rheumatological disease that affects multiple systems, and there are no predictors to know which system will be affected in the future. It could affect the mucocutaneous system. It could also present with hematological, rheumatological, neuronal, renal, pulmonary, and cardiac manifestations. SLE is prevalent in females, predominantly in the childbearing age group. The pharmacological therapy and bombarding pathophysiology of the disease lead to obstetrical and gynecological complications such as infertility, abortion, miscarriage, and stillbirth. Over the past decade, the autoimmune disease comorbidity increased eminently. One of the common associations is rheumatological diseases (like rheumatoid arthritis, Sjogren syndrome, and SLE) with gynecological diseases (e.g., endometriosis and uterine fibroids). SLE and endometriosis have strong associations, and the prevalence of each condition is relatively high among the female population. is a chronic disease triggered by inflammation, hormonal milieu, and other predisposing factors that lead to the fibrous tissue that lines the uterus (endometrial tissue) to be implanted at sites other than the uterus, commonly in the peritoneum and mesentery. The pathogenesis of this association remains unexplained. The approved theory is that their immune dysfunction is summarized by the elevated humoral and cell-mediated response, which leads to an attack to the epithelium, mesothelium, and Serosa and leads to fibrous tissue deposition in different sites other than the uterus. Statistical evaluations have shown a remarkable association between autoimmune diseases and both gynecological and nongynecological diseases.

Meta-Analysis Review
: Surgery remains the only possible curative treatment for advanced gastric cancer (AGC). Peritoneal metastases are estimated to occur in approximately 55-60% AGC patients. Greater omentum is the most common metastatic area in AGC. At present, omentectomy alone or bursectomy are usually carried out during gastric cancer surgery. We performed a meta-analysis in order to evaluate long-term and short-term outcomes among AGC patients, who have undergone radical gastrectomy with or without complete omentectomy (CO). : We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Meta-analysis was performed by use of RevMan (Computer program) Version 5.4. : The eight included studies covered an approximately 20 years long study period (2000-2018). Almost all included studies were retrospective ones and originated from Asian countries. Meta-analysis indicated gastrectomy without CO as significantly associated with longer 3-year (RR: 0.94, 95% CI: 0.90-0.98, = 0.005) and 5-year overall survivals (OS) (RR: 0.93, 95% CI: 0.88-0.98, = 0.007). Moreover, we found longer operative time (MD: 24.00, 95% CI: -0.45-48.45, = 0.05) and higher estimated blood loss (MD: 194.76, 95% CI: 96.40-293.13, = 0.0001) in CO group. : Non-complete omentectomy (NCO) group had a statistically greater rate in 3-year and 5-year OSs than the CO group, while the CO group had significantly longer operative time and higher estimated blood loss than the NCO group. Further randomized, possibly multi-center trials may turn out of paramount importance in confirming our results.

Meta-Analysis Review
PURPOSE
Complete mesocolic excision improves lymphadenectomy for right hemicolectomy and respects the embryological planes. However, its effect on cancer-free and overall survival is questioned. Therefore, we aimed to determine the potential benefits of the technique by performing a systematic review of the literature and meta-analysis of the available evidence.
METHODS
Web of Science, PubMed/Medline, and Embase were searched on February 22, 2023. Original studies on short- and long-term oncological outcomes of adult patients undergoing right hemicolectomy with complete mesocolic excision as a treatment for primary colon cancer were considered for inclusion. Outcomes were extracted and pooled using a model with random effects.
RESULTS
A total of 586 publications were identified through database searching, and 18 from citation searching. Exclusion of 552 articles left 24 articles for inclusion. Meta-analysis showed that complete mesocolic excision increased the lymph node harvest (5 studies, 1479 patients, MD 9.62, 95% CI 5.83-13.41, p > 0.0001, I 84%), 5-year overall survival (5 studies, 2381 patients, OR 1.88, 95% CI 1.14-3.09, p = 0.01, I 66%), 5-year disease-free survival (4 studies, 1376 patients, OR 2.21, 95% CI 1.51-3.23, p < 0.0001, I 0%) and decreased the incidence of local recurrence (4 studies, 818 patients, OR 0.27, 95% CI 0.09-0.79, p = 0.02, I 0%) when compared to standard right hemicolectomy. Perioperative morbidity was similar between the techniques (8 studies, 3899 patients, OR 1.04, 95% CI 0.89-1.22, p = 0.97, I 0%).
CONCLUSION
Meta-analysis of observational and randomised studies showed that right hemicolectomy with complete mesocolic excision for primary right colon cancer improves oncologic results without increasing morbidity/mortality. These results need to be confirmed by high-quality evidence and randomised trials in selected patients to assess who may benefit from the procedure.

Review
Multicystic peritoneal mesothelioma (MCPM) is a particularly rare and benign neoplasm that arises from the peritoneum in reproductive aged females. Its etiopathogenesis is still unclear. The current prevailing theory supports the idea that the tumor is the result of an excessive inflammatory process. Because of a lack of clinical and imaging presentation, the diagnosis is intricate, and heavily relies on case reports and short studies. A histological analysis with immunohistochemistry is required for a definitive diagnosis. To date, there is no standard treatment recommended for MCPM. However, some studies suggest proceeding with a cytoreductive surgery and a hyperthermic intraperitoneal chemotherapy combining CISPLATIN and DOXORUBICIN, due to a high incidence of recurrence rate after medical treatment or surgery alone and potential malignant transformation.

Review
BACKGROUND
Sarcoma may show similarities to malignant melanoma in terms of morphologic and immunohistochemical aspects, making it difficult to differentiate between these two neoplasms during the diagnostic process. This systematic review aims to summarize available evidence on cases of sarcoma that were initially diagnosed as melanoma.
METHODS
A comprehensive search of the MEDLINE/Pubmed, EMBASE, and SCOPUS databases was conducted through March 2023. We included case series and case reports of sarcoma patients that were initially diagnosed as malignant melanoma. PRISMA guidelines were followed.
RESULTS
Twenty-three case reports and four case series with a total of 34 patients were included. The clinical presentation was heterogeneous, and the most involved anatomical regions were lower limbs (24%), head/neck (24%), and upper limbs (21%). IHC positivity was reported for S100 (69%), HMB45 (63%), MelanA (31%), and MiTF (3%). The main reasons for a second assessment were unusual presentation (48%) and uncertain diagnosis (28%). EWSR1 translocation was investigated in 17/34 patients (50%) and found to be positive in 16/17 (94%). The final diagnosis was clear cell sarcoma (50%) or other soft tissue sarcomas (50%).
CONCLUSIONS
Melanoma and some histotypes of sarcoma share many similarities. In cases of atypical lesions, a second diagnosis should be considered, and ESWR1 translocation should be investigated.
